Abstract

This paper presents a novel label eraser that has the flat passband based on the Lyot-Sagnac filter for all optical label swapping (AOLS) networks. The cascaded performance of this filter is analyzed. The cascaded performance of the fiber-loop mirror (FLM) filter is also analyzed to bring into comparison with the Lyot-Sagnac filter. It is shown that power penalty of 1.48dB through four cascaded Lyot-Sagnac filters is obtained obviously prior to it of FLM filters that is 5.62dB. Meanwhile, the influences of the residual labels on the intermediate swapping node labels through the filters are also investigated, it is seen that the power penalty is only less 1dB when the optical power ratio of residual label to the new label signal arrives at - 8 dB.
